JOHN CARLYLE RAYMOND, OF NEW YORK, N. Y.

, To all whom it may concern: i

' Be it known that 1, JOHN CARLYLE RAY- MOND,-acitizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and In1- proved Tire, of which the following is a full, clear, and exact description. 7 The invention relates to tires, such as shownand described in the Letters Patentof the United States, No. 817,668, grantedto me on April 10, 1906.

The object of the present invention is to provide a new and improved tire, arranged to permit of quickly disconnecting the tire from the rim of the wheel, for repairs or other purposes, and replacing the tire and securely )cking it in place on the rim.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which ing side of the rim A, asplainly indicated iilj:

Fig. 1. To the other edge of the rim plate B is secured a down-turned flange lit by the use of screws C or other fastening devices,

the top of the flange B" being flush with the outer face of the rim plate B, so that this edge "of the rim plate'B is unobstructed, to

' allowo'f slipping the base plate D laterally over the rim plate B from the right, in Fig. 1. The base plate D is pr'ovided'at its outer edge With an upturned flange E correspendingv to the flange B and the inner edge of the said base plate D is adapted toifit under a rib B formed on the inner face of the flange B. A lining F of rubber or other suitable material is interposed between the rim plate B and the base plate I), to prevent any rattling when the parts are assembled, as shown in Fig. I

Specification of Letters Patent.

Application filed October 5,

Patented June 29, 1909. 1905. Serial no. 456,283.

' The tire as illustrated has the inner tube G and the casing I-I attached to the tire frame I in the manner more fully shown and described in the Letters Patent above referred to, so that further description oi the same is not deemed necessary, itbeing understood that this tire frame I is secured by screws J to the base plate D, the screws J being introduced from the inner surface of the base plate, as indicated in Fig. 1 The tire is also provided with a cushion ii of rubber or other suitable material, and forming a seat for the inner side of the inner tube (:x, so that when the tire is collapsed the cushion K tends to avoid any injury to the inner tube G and the casing A.

In order to hold the base plate D and the tire frame I and easing H containing the inner tube G in position on the rim plate B, a number of locking devices are provided, preferably four, spaced equidistant apart, and each consisting of a catch L fulcrumed at L on the rim. plate B, the shoulder L of the catch being adapted to snap into an. apei ture D formed. in the base plate D, as shown in Figs. 1 and 3. When the shoulder l engages the aperture D, it prevents latoral displacement of the base plate 1) to the right, it being understood that lateral displacementto the left is prevented by the.

inner edge of the base plate D abutting against the upturned flange 13 under the rib B.

The free end of the catch L is pivotally connected with a rod or handle mounted to slide in a bearing 0, screwed or otherwise attached to the rim A and extending to the under surface thereof, and the said rod N has a reduced portion N, terminating in a head- N normal y abutting against thcoul'cr end of the bearing O, as plainly shown in Fig. 1. A spring l. is coile l around the reduced portion N within tlle bearing 0 and presses against a shouldm' N between the rod N and the reduced portion N, to normally hold the with the aperture D of the base plate D.

Then it is desired to unlock the base plate D, the heads N 2 are pulled out-ward, preier- 1 .shoulder L of the catch L in engagement tached thereto laterally to the right and over the rim A of the wheel. The too Q is prefer-v is, until the desired repairs have been made to the tire, after which the tire is replaced on the rim plate B, and then the tools Q are removed, to allow the springs l? to swing the catches L outward into lockin position, that is, to reengage the shoulders 2 with the ap-' ert'ures D. I

From the foregoing it will be seen that When the shoulders L of the catches L engage the apertures D of the base plate D, then the base plate D and the parts supported thereon are held, against lateral movement to the right and also against a creeping in a longitudinal direction on the rim plate The device is very simple and durable in construction and the parts can be very eonveniently assembled and disconnected for repairs and other purposes. Y

Having thus described my invention, I claim as new and desire to secure by Letters Patent: i

1. In combination, a rim having a rim plate provided at one edge With a down-,

turned flange and at the opposite edge with an upturned and a downturned flange, the upturned flange being provided with a rib,

, a base plate adapted to be sli'iped over the edge of the rim plate having ut one flange onto the latter, the inner edge of the said base plate engaging the said 'rim plate flange below the rib thereof, the outer edge of the said base plate having an upturned flange, a tire frame removably secured to the said base plate and carrying a tire casing, and pivoted and spring )ressed locking devices on the said rim and its rim, )late and engaging the said base plate to locli the same against lat- I oral and peripheral movement.

2. In combination, a rim having a rim plate rovided at one edge With a flange, a slotte base plate adapted to be slipped over sas es the non-flanged edge of the rim plate onto 'the'latter, theinner edge of the said base plate engaging the said rim plate flange, the outer'edge of the said base plate having a flange, a tire frame removably secured to the said base plate and carrying a tlI'fiCilSlllg, a catch pivoted on the said rim late and adapted to engage the edge of a s 0t in the said base plate to hold the latter against lat- ,eral and peripheral movement, andv aspring-J pressed handle radially slidable in the said rim, and connected at its outer end with the said catch, the inner head end of the handle extendin on the inside of the rim formanipup i. said catch.

lating 3. .n corn b1nat1on, an apertu red rim'having a rim plate provided at one edge with a flange, a slotted base plate adapted to be slipped over the non-flanged edge ofthe rim plate onto the latter, the inner edge of the said base plate engaging the said. rim plate flange, the outer edge of thesaid base plate having a flange, a tire frame rem'ovably secured to the said base plate and carrying a tire casing, a catch pivoted atone end to the said rim plate and adapted to'engage the edge of a slot in the said base plate: to hold the latter against lateral and peripheral movement, a handle pivotally connected at its outer end. with the free endof said catch and radially slidable in the aperture of said rim, the inner end ofthe handle terminal ing in a head for manipulating'thesaid rah-h, and a spring surrounding-the said handle -lll the aperture of the rim and normally holding the catch in engagement With the said base late.

In testimony whereof I have signed 111)" name to this specification in the presence ol' two subscribing witnesses;
